So you've made it big time, you've got it all. The car, the toys and a big house with a whole-home audio system. The thing is, as great as your CasaTunes Music Server is with its in-wall and in-ceiling speakers, the ability to integrate with the latest and greatest AirPlay devices is still missing. Well it was anyways, as the new CasaTunes Air you can stream any content from your CasaTunes Music Server to all your speakers, AirPlay or any other. Even better, the music can be on your iOS device or stored on your server -- but you can still control the whole thing from your phone or tablet. CasaTunes Air is a feature of the new CasaTunes version 4, which we can only assume is a free upgrades for existing CasaTunes Music Servers.
